SS-4 Black (M107)

The Saricami SS-4 is a perfect alternative to the Benelli M4; actually, it’s an exact clone! In testing we interchanged parts with a Benelli M4 and both shotguns operated perfectly.  

The SS-4 is gas-operated and is designed around an entirely new design called the "auto-regulating gas-operated" (ARGO) system. The short-stroke design uses two self-cleaning stainless steel pistons located just ahead of the chamber to function opposite a rotating bolt, thereby eliminating the need for the complex mechanisms found on other gas-actuated automatics. The ARGO incorporates only four parts: two symmetrical fore-end shrouds containing two small steel pistons that push directly against the bolt.

Additionally, the weapon is self-regulating for use with shotshells of varying lengths and power levels. It can fire 2.75 in (70 mm) and 3 in (76 mm) shells of differing propellant loads without any operator adjustments and in any combination.
